​​​​​​​​Aliso Canyon Updates and Reso​urces

After putting numerous safeguards​ in place to protect public safety and the environment, the Division of Oil, Gas, and Geothermal Resources and California Public Utilities Commission have concurred that natural gas injection may resume at the Aliso Canyon storage facility. Before, and soon after, resuming injection, Southern California Gas must comply with the requirements of an order issued by the Division of Oil, Gas, and Geothermal Resources (DOGGR), including flyovers to check methane levels.

Since the leak was plugged at the Los Angeles County facility 17 months ago, significant improvements and upgrades have been made to infrastructure, testing, operations, and monitoring to ensure safe operations. The Division completed a comprehensive safety review at Aliso Canyon in January, consulting with the nationally recognized experts from the Lawerence Livermore, Lawerence Berkeley and Sandia National Laboratories on extensive site inspections and review of Southern California Gas's testing. The facility will operate with significantly reduced storage capacity and maximum injection pressures.
